ʻO ka Paipu Alloy Copper-Nickel Premium - Ke Kū'ē Kai Kai Kiʻekiʻe
Paipu Keleawe Keʻokeʻo (Cupro-Nickel) - Hoʻohui ʻenehana
Hana ʻia kā mākou mau paipu cupro-nickel ma o ke kaʻina hana piha o ka hoʻolei mau ʻana i ka ʻaoʻao kiʻekiʻe, ka hana anu multi-pass, a me ka mālama wela lewa pale e hōʻoia i ka haku mele like ʻana o ka metala, ka hoʻonohonoho ʻana o ka palaoa i hoʻomaʻemaʻe ʻia, a me ka microstructure paʻa.
Kahe kaʻina hana koʻikoʻi: Hoʻoheheʻe ʻana i ka hoʻokomo ʻana i ka vacuum → Hoʻolei mau ʻana i ka pae (billet semi-hoʻomau) → Extrusion wela kiʻekiʻe → ʻŌwili/kiʻi anu multi-pass → Annealing waena he nui ma lalo o ka lewa pale → Hoʻopau hope loa → 100% eddy current + hoʻāʻo ultrasonic (e like me ka mea e pono ai).
ʻOi aku ka maikaʻi o ka mana o ka maikaʻi ma mua o nā kūlana aupuni a me ASTM me nā kikoʻī i loko o ka hale:
● Hoʻohuihui kemika: Ua hōʻoia ʻia kēlā me kēia wela e ka spectrometer heluhelu pololei; ʻo ka loli o nā mea nui (Cu+Ni+Fe+Mn) i kāohi ʻia i loko o ±0.05%
● Ka nui o ka hua: Mālama mau ʻia ma 0.015–0.035 mm, ʻaʻohe hua i hui ʻia
● Nā waiwai mīkini: Hoʻāʻo piha ʻana o ka ikaika tensile, ka ikaika hua, a me ka elongation; coefficient o ka loli (CV) < 3%
● Nā hoʻomanawanui ana: OD ±0.015 mm, WT ±0.008 mm, ovality ≤ 0.02 mm
● Hoʻopau ʻili: ʻIli o loko a me waho Ra ≤ 0.4 μm, ʻaʻohe kala oxidation, nā ʻōpala, a i ʻole nā māwae
● NDT: 100% hoʻāʻo ʻana o ke au eddy e like me EN 1971 Papa A; loaʻa ka hoʻāʻo ultrasonic ma ke noi ʻana
● Ka hoʻomaʻemaʻe kūloko: ʻOi aku ka maikaʻi o ka hoʻomaʻemaʻe ʻili o loko ma mua o ka IGC-Test Grade 1, kūpono no ka hydrogen kiʻekiʻe, nā refrigerants, a me nā mea koʻikoʻi ʻē aʻe
Ua hoʻohana pono ʻia kēia mau ʻōmole i ka ʻenekinia moana, nā paipu wai kai moku, nā mea hoʻololi wela, nā laina mea hana mana nukelea, a me nā ʻōnaehana mālama a me ka halihali hydrogen kiʻekiʻe. Ua hoʻokumu mākou i nā pilina hoʻolako lōʻihi me nā ʻoihana alakaʻi ʻoihana he nui a mālama i kahi mana makahiki o 8,000 tons o nā ʻōmole cupro-nickel hana kiʻekiʻe. Loaʻa ka hana maʻamau e like me nā kiʻi a nā mea kūʻai aku a i ʻole nā kūlana maʻamau e like me AMS 4574, CuNi30, C71500, BNi-2, a pēlā aku.
